Question

ПОМОГИТЕ ПОЖАЛУЙСТА!!!!!!! Укажите верные утверждения: 1) a : b = c ⇐⇒ c · a = b 2) a : b = c ⇐⇒ c · b = a 3) Число k на 2 больше числа m ⇐⇒ k = m + 2 4) Число k на 2 больше числа m ⇐⇒ m = k + 2 5) 2 (x - 3) = x ⇐⇒ 2x - 3 =x 6) 2 (x - 3) = x ⇐⇒ x = 6

Answer 1

Ответ: a : b = c ⇐⇒ c · a = b

Число k на 2 больше числа m ⇐⇒ k = m + 2

2 (x - 3) = x ⇐⇒ 2x - 3 = x

Пошаговое объяснение:

Answer 2

1) a : b = c ⇔ c · a = b This statement is false. The correct statement is a : b = c ⇔ c · b = a.

2) a : b = c ⇔ c · b = a This statement is true. It states that a ratio equality is equivalent to the corresponding product equality.

3) Число k на 2 больше числа m ⇔ k = m + 2 This statement is true. It states that adding 2 to number m is equivalent to setting k equal to m + 2.

4) Число k на 2 больше числа m ⇔ m = k + 2 This statement is false. The correct statement is m = k - 2. Subtracting 2 from number k is equivalent to setting m equal to k - 2.

5) 2(x - 3) = x ⇔ 2x - 3 = x This statement is false. The correct statement is 2(x - 3) = x ⇔ 2x - 6 = x. Distributing the 2 to both terms inside the parentheses.

6) 2(x - 3) = x ⇔ x = 6 This statement is true. It states that solving the equation 2(x - 3) = x results in x = 6.

I hope this helps! Let me know if you have any further questions.
